LM331 PDF

The LM/LM family of voltage-to-frequency converters are ideally suited for use in simple low-cost circuits for analog-to-digital conversion, precision. Texas Instruments LM Series Voltage to Frequency & Frequency to Voltage are available at Mouser Electronics. Mouser offers inventory, pricing. A Voltage to Frequency (VTF) converter is a circuit, which converts a voltage level to a linearly proportional frequency. A special configuration of the LM IC.

But in simulation with 5V it doesn’t work. LM should work with 5V supply. Yes sure, I tried 1V 0.

LM331 Voltage to Frequency Converter Circuit

From page 4, 7. But on the on the other hand, on the first page it says “Operates on Single 5-V Supply” But it doesnt work at 5V supply in simulation. While Vs at 5V, did u ensure that your input does not cross 5V? Sign up using Email and Password. Can someone explain me how this circuit works? What else sets what here?

LM Voltage to Frequency Converter Circuit

It works when I use 10V supply. Post as a guest Name.

What is that poti for? Yes so I can use it with 12V supply as well then since Vs is max 40V. Sign up or log in Sign up using Google.

I mean C1 and R1 sets the frequency but thats all I know.

Since LM works at 5V supply, I can scale This will give you a square wave at half lm331 frequency.

How can I modify this circuit so I can run the simulation for 5V supply? I came across this circuit and this forum. If the actual labels are 1 and 5then you may wish to change the directive to.

But I’m getting 5V constant output when I use 5V supply. The LM works by putting out fixed-width pulses and there is nothing you can do to change this. And are the values lm313 components dependent on supply voltage?

I followed the instructions to use LM in LTspice and simulated the circuit below:
